Filtrate flows from the proximal convoluted tubule directly into the distal convoluted tubule.

Proximal Convoluted Tubule

A portion of the nephron in the kidney where a major amount of ion and water reabsorption from the filtrate occurs, playing a key role in the regulation of pH, electrolyte balance, and blood pressure.

Distal Convoluted Tubule

A portion of the nephron in the kidney involved in the selective reabsorption and secretion, playing a key role in regulating the body's salt and water balance.
